Let’s delve into the critical parameters of these bags and how they align with diverse industrial requirements.
Exploring Key Parameters of Block Bottom PP Bags
The performance and versatility of Block Bottom Valve Bags largely depend on their design and material specifications. Below, we explore the crucial product parameters that define these bags:
1. Thickness
The thickness of Block Bottom sacks directly influences their durability and load-bearing capacity. Commonly ranging from 60 microns to 150 microns, the appropriate thickness is chosen based on the type of product being stored or transported.
- Lightweight goods: 60–90 microns
- Medium-weight goods: 90–120 microns
- Heavy-duty applications: 120–150 microns
2. Weight
The weight of the bag itself affects logistics efficiency and usability. Designed to balance strength with lightweight features, these bags usually weigh between 50 grams to 150 grams depending on their size and thickness.
3. Size Variations
One of the most versatile aspects of BOPP Block Bottom Bags is their adaptability in size. From small bags for retail packaging to large sacks for industrial applications, typical sizes include:
- Small: 250 mm × 300 mm × 90 mm
- Medium: 350 mm × 450 mm × 120 mm
- Large: 450 mm × 600 mm × 150 mm Custom dimensions can also be tailored to meet specific client needs, ensuring flexibility for any industry.
4. Load-Bearing Capacity
The structural integrity of these bags is evident in their load-bearing capacities. With reinforced seams and the block bottom design, they can support weights ranging from 5 kg to 50 kg.
- Agriculture: 10–25 kg (fertilizer, grains)
- Construction: 25–50 kg (cement, sand)
- Food industry: 5–15 kg (flour, sugar)
5. Material Composition
Made from polypropylene (PP) and laminated with BOPP films, these bags are resistant to moisture, UV rays, and abrasion. They offer unmatched durability while being environmentally friendly.
